Scope
What we test in Jefferson County
Concrete testing services
Fresh concrete sampled and tested at the pour — slump, air content, unit weight, and temperature — with cylinders and beams cast on site and broken in the laboratory on the schedule your specification calls for.
ASTM C172ASTM C143ASTM C231ASTM C173ASTM C138ASTM C1064ASTM C31ASTM C39
Aggregate testing services
Gradation, fines content, specific gravity and absorption, unit weight, abrasion resistance, and stockpile moisture for concrete, base course, and backfill aggregates.
ASTM D75ASTM C136ASTM C117ASTM C127ASTM C128ASTM C29ASTM C131ASTM C566
Soil compaction and density testing
Standard and modified Proctor curves in the laboratory and in-place density by nuclear gauge on every lift, so fill, subgrade, and trench backfill are documented against the specified percent compaction.
Soil classification and index testing
Sieve and hydrometer gradation, Atterberg limits, moisture content, specific gravity, and USCS classification for earthwork acceptance, select-fill verification, and geotechnical reports.
ASTM D6913ASTM D7928ASTM D1140ASTM D4318ASTM D2216ASTM D854ASTM D2487
Soil corrosivity testing
pH and electrical resistivity of backfill for MSE walls, pipelines, and buried structures, reported against the specification limits for metallic and geosynthetic reinforcement.
Special inspection (IBC Chapter 17)
ICC-certified special inspectors for reinforced concrete and soils, reporting to the building official alongside the materials test results, so one agency covers both requirements.

Local conditions
Construction materials testing conditions in Jefferson County
Jefferson County's construction landscape is demanding by nature. Louisville's position as a major river-crossing and logistics hub has sustained steady commercial, industrial, and infrastructure development, while the region's underlying geology — a mix of residual clay soils derived from limestone bedrock and alluvial deposits along Ohio River tributaries — creates real variability in bearing capacity, shrink-swell behavior, and moisture sensitivity. Concrete work through Kentucky's humid summers and freeze-thaw winters adds another layer of risk: placements that skip fresh concrete verification can produce cylinders that don't tell the full story when temperatures swing. Our field technicians, holding ACI and NICET certifications, are dispatched to Jefferson County projects to perform ASTM-compliant testing of concrete, soil, and aggregate from placement through final compaction verification. The laboratory operates under a documented quality system. Reports are written to be defensible — clear chain of custody, correct ASTM designations, and data your engineer of record can act on without follow-up calls.
Jefferson County soils often include high-plasticity clays that are sensitive to moisture fluctuation, making accurate Proctor baseline testing (ASTM D698 or D1557) and field density verification essential before structural fill is accepted. Kentucky's climate — with notable freeze-thaw cycles and warm, humid construction seasons — means concrete air content and slump documentation at the point of placement is not a formality but a practical protection against premature deterioration.
FAQ · Jefferson County
Jefferson County has a lot of clay fill on my site. Which compaction test standard applies, and how do you establish the baseline?
For cohesive soils like the high-plasticity clays common in Jefferson County, compaction control starts with a laboratory Proctor test — either Standard Proctor (ASTM D698) or Modified Proctor (ASTM D1557), depending on your specification. That test establishes the maximum dry density and optimum moisture content against which field nuclear density gauge readings (ASTM D6938) are compared to confirm the specified percent compaction has been achieved.
What concrete air content testing do you perform, and why does it matter specifically during Kentucky's winters?
We measure air content using a pressure meter per ASTM C231 as part of every fresh concrete testing sequence. In Kentucky, where freeze-thaw cycles are routine, adequate entrained air — typically 5–7% for exposed flatwork per ACI 318 exposure class requirements — is the primary defense against scaling and internal cracking. A documented air content result at the point of placement gives your team defensible evidence that the mix met spec before the concrete went in the forms.
My Louisville area project has a geotechnical report calling out expansive soils. What testing do you do to verify subgrade conditions before we place concrete or structural fill?
We perform soil classification testing per ASTM D2487 (Unified Soil Classification System) to characterize material in the field and laboratory. Where swell potential is a concern, moisture-density relationships (ASTM D698 or D1557) and Atterberg limits (ASTM D4318) help characterize plasticity. That data, paired with field density testing during fill placement, gives the project team and the engineer of record the documentation needed to confirm subgrade preparation meets plan requirements.
How fast can a technician be on site in Jefferson County?
Jefferson County work is dispatched through our Nashville, TN regional hub. Scheduled visits are set up by phone at (346) 420-5425; multi-day placements and full-time project assignments are scheduled through a proposal request.
Which office covers materials testing in Jefferson County, KY?
Field work in Jefferson County is dispatched through the Nashville, TN regional hub, about 155 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Jefferson County projects.
Are the technicians you send to Jefferson County certified?
Yes. Concrete technicians hold ACI Concrete Field Testing Technician Grade I; soils and laboratory technicians hold NICET Construction Materials Testing certifications; special inspection is performed by ICC-certified special inspectors. Where Kentucky agencies or owners require state-specific certifications, those are confirmed in the proposal.
